git-bugreport already rejected unrecognized flag arguments, like
`--diaggnose`, but this doesn't help if the user's mistake was to forget
the `--` in front of the argument. This can result in a user's intended
argument not being parsed with no indication to the user that something
went wrong. Since git-bugreport presently doesn't take any positionals
at all, let's reject all positionals and give the user a usage hint.

This is another step towards letting us remove the include of cache.h in
strbuf.c. It does mean that we also need to add includes of abspath.h
in a number of C files.

Dozens of files made use of gettext functions, without explicitly
including gettext.h. This made it more difficult to find which files
could remove a dependence on cache.h. Make C files explicitly include
gettext.h if they are using it.
However, while compat/fsmonitor/fsm-ipc-darwin.c should also gain an
include of gettext.h, it was left out to avoid conflicting with an
in-flight topic.

For a lot of uses of UNLEAK() it would be quite tricky to release the
memory involved, or we're missing the relevant *_(release|clear)()
functions. But in these cases we have them already, and can just
invoke them on the variable(s) involved, instead of UNLEAK().
For "builtin/worktree.c" the UNLEAK() was also added in [1], but the
struct member it's unleaking was removed in [2]. The only non-"int"
member of that structure is "const char *keep_locked", which comes to
us via "argv" or a string literal[3].
We have good visibility via the compiler and
tooling (e.g. SANITIZE=address) on bad free()-ing, but none on
UNLEAK() we don't need anymore. So let's prefer releasing the memory
when it's easy.
For "bugreport", "worktree" and "config" we need to start using a "ret
= ..." return pattern. For "builtin/bugreport.c" these UNLEAK() were
added in [4], and for "builtin/config.c" in [1].
For "config" the code seen here was the only user of the "value"
variable. For "ACTION_{RENAME,REMOVE}_SECTION" we need to be sure to
return the right exit code in the cases where we were relying on
falling through to the top-level.
I think there's still a use-case for UNLEAK(), but hat it's changed
since then. Using it so that "we can see the real leaks" is
counter-productive in these cases.
It's more useful to have UNLEAK() be a marker of the remaining odd
cases where it's hard to free() the memory for whatever reason. With
this change less than 20 of them remain in-tree.

Fix various inconsistencies between command SYNOPSIS and the
corresponding -h output where our translatable labels didn't match
up.
In some cases we need to adjust the prose that follows the SYNOPSIS
accordingly, as it refers back to the changed label.

The whitespace padding of alternatives should be of the form "[-f |
--force]" not "[-f|--force]". Likewise we should not have padding
before the first option, so "(--all | <pack-filename>...)" is correct,
not "( --all | <pack-filename>... )".

in aac0e8ffeee (builtin/bugreport.c: create '--diagnose' option,
2022-08-12): We need to close the "[" we opened. The
corresponding *.txt change did not have the same issue.

Fix the incorrect "[-o | --option <argument>]" syntax, which should be
"[(-o | --option) <argument>]", we were previously claiming that only
the long option accepted the "<argument>", which isn't what we meant.
This syntax issue for "bugreport" originated in
238b439d698 (bugreport: add tool to generate debugging info,
2020-04-16), and for "diagnose" in 6783fd3cef0 (builtin/diagnose.c:
create 'git diagnose' builtin, 2022-08-12), which copied and adjusted
"bugreport" documentation and code.
In the case of "Documentation/git-stash.txt" and "builtin/stash.c"
this is not a "doc txt & -h consistency" change, as we're changing
both versions, doing so here makes a subsequent change smaller.
In that case fix the incorrect "[-o | --option <argument>]" syntax,
which should be "[(-o | --option) <argument>]", we were previously
claiming that only the long option accepted the "<argument>", which
isn't what we meant.
The "stash" issue has been with us in both the "-h" and *.txt versions
since bd514cada4b (stash: introduce 'git stash store', 2013-06-15).
We could claim that this isn't a syntax issue if a "vertical bar binds
tighter than option and its argument", but such a rule would change
e.g. this "cat-file" SYNOPSIS example to mean something we don't:
... [<rev>:<path|tree-ish> | --path=<path|tree-ish> <rev>]
We have various other examples where the post-image here is already
used, e.g. for "format-patch" ("-o"), "grep" ("-m"),
"submodule" ("set-branch -b") etc.

Change the documentation and -h output for those built-in commands
where both the -h output and *.txt were lacking in word-wrapping.
There are many more built-ins that could use this treatment, this
change is narrowed to those where this whitespace change is needed to
make the -h and *.txt consistent in the end.
In the case of "Documentation/git-hash-object.txt" and
"builtin/hash-object.c" this is not a "doc txt & -h consistency"
change, as we're changing both versions, doing so here makes a
subsequent change smaller.

Create a '--diagnose' option for 'git bugreport' to collect additional
information about the repository and write it to a zipped archive.
The '--diagnose' option behaves effectively as an alias for simultaneously
running 'git bugreport' and 'git diagnose'. In the documentation, users are
explicitly recommended to attach the diagnostics alongside a bug report to
provide additional context to readers, ideally reducing some back-and-forth
between reporters and those debugging the issue.
Note that '--diagnose' may take an optional string arg (either 'stats' or
'all'). If specified without the arg, the behavior corresponds to running
'git diagnose' without '--mode'. As with 'git diagnose', this default is
intended to help reduce unintentional leaking of sensitive information).
Users can also explicitly specify '--diagnose=(stats|all)' to generate the
respective archive created by 'git diagnose --mode=(stats|all)'.

Make githooks(5) the source of truth for what hooks git supports, and
punt out early on hooks we don't know about in find_hook(). This
ensures that the documentation and the C code's idea about existing
hooks doesn't diverge.
We still have Perl and Python code running its own hooks, but that'll
be addressed by Emily Shaffer's upcoming "git hook run" command.
This resolves a long-standing TODO item in bugreport.c of there being
no centralized listing of hooks, and fixes a bug with the bugreport
listing only knowing about 1/4 of the p4 hooks. It didn't know about
the recent "reference-transaction" hook either.
We could make the find_hook() function die() or BUG() out if the new
known_hook() returned 0, but let's make it return NULL just as it does
when it can't find a hook of a known type. Making it die() is overly
anal, and unlikely to be what we need in catching stupid typos in the
name of some new hook hardcoded in git.git's sources. By making this
be tolerant of unknown hook names, changes in a later series to make
"git hook run" run arbitrary user-configured hook names will be easier
to implement.
I have not been able to directly test the CMake change being made
here. Since 4c2c38e800 (ci: modification of main.yml to use cmake for
vs-build job, 2020-06-26) some of the Windows CI has a hard dependency
on CMake, this change works there, and is to my eyes an obviously
correct use of a pattern established in previous CMake changes,
namely:
- 061c2240b1 (Introduce CMake support for configuring Git,
2020-06-12)
- 709df95b78 (help: move list_config_help to builtin/help,
2020-04-16)
- 976aaedca0 (msvc: add a Makefile target to pre-generate the Visual
Studio solution, 2019-07-29)
The LC_ALL=C is needed because at least in my locale the dash ("-") is
ignored for the purposes of sorting, which results in a different
order. I'm not aware of anything in git that has a hard dependency on
the order, but e.g. the bugreport output would end up using whatever
locale was in effect when git was compiled.

Move the find_hook() function from run-command.c to a new hook.c
library. This change establishes a stub library that's pretty
pointless right now, but will see much wider use with Emily Shaffer's
upcoming "configuration-based hooks" series.
Eventually all the hook related code will live in hook.[ch]. Let's
start that process by moving the simple find_hook() function over
as-is.

prefix_filename() returns newly allocated memory, and strbuf_addstr()
doesn't take ownership of its inputs. Therefore we have to make sure to
store and free prefix_filename()'s result.
As this leak is in cmd_bugreport(), we could just as well UNLEAK the
prefix - but there's no good reason not to just free it properly. This
leak was found while running t0091, see output below:
Direct leak of 24 byte(s) in 1 object(s) allocated from:

To generate its filename, the 'git bugreport' builtin asks the system
for the current time with 'localtime()'. Since this uses a shared
buffer, it is not thread-safe.
Even though 'git bugreport' is not multi-threaded, using localtime() can
trigger some static analysis tools to complain, and a quick
$ git grep -oh 'localtime\(_.\)\?' -- **/*.c | sort | uniq -c
shows that the only usage of the thread-unsafe 'localtime' is in a piece
of documentation.
So, convert this instance to use the thread-safe version for
consistency, and to appease some analysis tools.

There's no reason that bugreport has to be a separate binary. And since
it links against libgit.a, it has a rather large disk footprint. Let's
make it a builtin, which reduces the size of a stripped installation
from 24MB to 22MB.
This also simplifies our Makefile a bit. And we can take advantage of
builtin niceties like RUN_SETUP_GENTLY.
